Description

Wärmeisolierter Autogenbrenner Im Patent 939 141- ist ein Autogenbrenner unter Schutz gestellt, der zum Schutz gegen das radiale Eindringen von Wä -me durch eine wärmeisolierende Hü111e und einen geschlossenen Mantel .hoher Tem_peratutbe: tändigkeit und relativ geringer Wärmeleitung derart geschützt ist, daB die kritische Temperatur des exothermen Azetylenzerfalls im Brennerrohr nicht erreicht wird. Weiterhin sind Mittel vorgesehen, die Ansammlung von. Gasresten und Wärmestauung im Brennerrohr zu verhindern, sowie das Eindringen von Wärme in axialer Richtung durch Vorziehen des Isoliermantels bis in die Nähe der Brennerspitze zu erschweren.Heat-insulated oxy-fuel burner In patent 939 141- is an oxy-fuel burner placed under protection, the protection against the radial penetration of heat by a heat-insulating sleeve and a closed coat .high tem_peratutbe: resistance and relatively low heat conduction is protected in such a way that the critical Temperature of the exothermic acetylene decomposition in the burner tube is not reached. Farther funds are provided for the accumulation of. Gas residues and heat build-up in the burner tube to prevent, as well as the penetration of heat in the axial direction by pulling forward of the insulating jacket up to the vicinity of the burner tip.

Nach der Erfindung wird ein solcher Brenner noch in der Weise verbessert, da<ß der Metallquerschnitt des Mischrohres und damit seine Wärmeleitung von der Brennerspitze zur Mischdüse hin stetig oder stufenweise zunimmt. Auf diese Weise wird ein Wärmestau mit Sicherheit verhindert und die radial oder axial etwa eingedrungene Wärme rasch abgeführt.According to the invention, such a burner is improved in such a way that da <ß the metal cross-section of the mixing tube and thus its heat conduction from the Burner tip increases steadily or gradually towards the mixing nozzle. In this way will a heat build-up is prevented with certainty and that which has penetrated radially or axially Heat dissipated quickly.

Eine weitere Verbesserung des Brenners nach dem Hauptpatent wird dadurch erzielt, daß die wärmeisolierende Hülle um das Mischrohr geschichtet ausgeführt wird, weil bekanntlich geschichtete Isolierstoffe einen erhöhten Wärmedurchga-ngswiderstand aufweisen.A further improvement of the burner according to the main patent is thereby achieved that the heat-insulating sleeve carried out layered around the mixing tube is because layered insulating materials are known to have an increased thermal resistance exhibit.
